On the last page (I read the danish translation, so I'm not sure if its totally accurate use of words), Nathan said something like "Say hello/goodbye to Kitty for me" to Bart. Ive already wrote to mr. Stroud, but do you think Bart ever got the chance to do so?

I don't think so. Nathaniel died right afterwards and Bartimaeus would have gone back to the Other Place. The only way would be if Kitty summoned Bartimaeus at a later time, which I don't think she would, (although it would make a great story).
Still, I think Kitty knew it was good-bye in retrospect.

kitty won't summon bart afterwards, everybody will think bart died with nat

She might try to summon Bart, I don't think she would give up so easily. Although I dunno how thrilled Bart would be at that prospect.

I hope she tried to summon bart. But alas, I may just be dreaming, I am also one of the few naive beings, that still clings to that nat someway survived. Stroud actually said on his facebook at some point, that Nat might maybe appear again, maybe in the some other other way or context.

Well, he could appear in textbooks a few years after PG, but apart from that I think you're clinging a bit desperately to a very thin tread.

I wanted it to happen, back before I became a realist. That was why I wrote a Fanfiction on Kitty summoning our Bart and Bart passing on Nathaniel's simple message.
However, Kitty *could* have linked Nathaniel's death to the incident of Ptolemy's demise. She knew Ptolemy's story- how he saved Bart at the last minute by dismissing him- so she may have inferred that Nathaniel would do the same. It all depends on how many brain cells she has and how desperate she was.

Well, she could have except that I don't think she'd get that desperate. Would she really summon Bartimaeus, if she knew he wanted to be left alone?

Bartimaeus may have tolerated or even welcomed a summoning by Kitty; all she would have needed was a quick chat to ensure that he was still alive. Besides, he enjoyed it when Ptolemy set him free to explore the Earth. Kitty could do the same; after all, it was hinted at at some point in the series that Bart missed seeing the wonders of Earth.

Yes, but would she? She might summon him for a quick chat, but I think she'd leave him alone after that.

If he asked her to, then I believe that she would oblige by his wishes. However, that would still give him the change to pass on Nat's simple "Hello".

...Which should actually be a goodbye.

Aye, but Nat had told Barti to "Say hello to Kitty for me", not a goodbye. And yet, the hello would also be considered a goodbye- so Barti would be saying "Hello" as a parting address. Rather paradoxical, if you ask me...

Good thing I like paradoxes, then :P

What is the answer to this question?
What will happen if an unstoppable force meets an immovable object?
If you try to fail and you succeed, then what have you done?
The below sentence is false.
The above sentence is true.

We have something in common- I love paradoxes as well ^-^

what is the question to this answer?
Both objects sporadically combust :P
You've just failed epically, of course
Neither are true or false- they just are

I love trying to solve them...

I love (attempting to) answer the unanswerable as well.

1. I got the same answer as well.
2. Hmm...But what if the object is indestructible as well? (I can present my theory after you give yours)
3. Or you've succeeded at failing :P

2. I suppose it would depend on the angle of collision; the unstoppable force can be steered by the unmovable object to be unstoppable into another direction.
3. you've succeded at failing, but since you were trying to do that, you've failed big time.

2. That was my theory as well. However, if the unstoppable force is merely a force that lacks a solid object behind it, I think that the force may simply pass through the object. In other words, not much would occur.
...Although, in the real world, such an event would not occur simply because such a force and such an object do not exist- it would be required to have infinite velocity.

It would go back in time, if it was fast enough, and if the force and the object suddenly started existing at the same time, with the force racing towards the object, it'd go back in time, so there's a possibility that they wouldn't meet at all.
